Abstract

The invention relates to a method for quickly cultivating mulberries of Strong Mulberry Number 1. The method includes fertilizing after mulberry seedlings are planted; in spring of the first year, pruning at positions being 20cm away from the ground after field planting; in early May, performing bud thinning, namely selecting and remaining 2-3 strong buds which healthy and strong in growing of upper portions and uniform in insertion position for each plant and cultivating the buds on each plant to be 2-3 branches; in early July, pinching at positions being 45cm away from the ground, cultivating to be first sub-branches, and taking pruned green leaves as leaves for summer silkworms of five years old; in early August, performing bud thinning, retaining 4-6 branches for each plant, and cultivating to be second sub-branches; in late November, performing forced top clipping; in spring of the second year, without performing spring pruning, performing summer pruning and fist determining at positions being 65cm away from the ground until the late May, retaining 3-5 fists for each plant, and cultivating to be tree shapes. By the method, the mulberries are exuberant in growing and high in annul leaf yield when fertilizer-water management conditions are good, and can be quickly cultivated within two years; the method is reliable in technology, the objective of early production and early harvesting of silkworm raisers can be achieved, and leaves obtained by summer pruning can be used as leaves for spring silkworms, so that utilization rate of mulberry leaves is increased, and income of the silkworm raisers is increased.

Description

Strong mulberry tree of mulberry is formed method fast

Technical field:

The present invention relates to mulberry tree field of planting, form fast method more specifically to mulberry tree of strong mulberry.

Background technology:

Conventionally mulberry sapling is planted growing into forest operation needs the time of 3 years, before appearance, silk market conditions change unpredictably, Cocoon Price is all changing every year, and price fluctuation amplitude is also larger, in the time expecting rising market, silkworm raiser plants mulberry to change the enthusiasm of mulberry surging, but after 3 years, mulberry tree grows into forest and may glide by Cocoon Price while operation, and silkworm raiser takes in corresponding minimizing.If by the improvement of technology, shorten mulberry tree and grow into forest the time of going into operation, 1 year output, not only makes silkworm raiser do sth. in advance income in advance, and the market conditions opportunity that can win, increases silkworm raiser's income.The income early of early going into operation be numerous silkworm raisers in the urgent need to.No. 1, the New Mulberry Variety of promoting mainly at present has farming and sericulture No. 14, strong mulberry etc.And the representative of strong No. 1 conduct New Mulberry Variety of new generation of mulberry, approved by numerous silkworm raisers and silkworm industry worker, particularly slow, drought-enduring, the spring bud of its autumn leaves sclerosis is avoided the merits such as freeze injury, the large output of leaf is high, growth potential is prosperous, be applicable to very much the mulberry field transformation plantation of unfavorable irrigation, be from now on refining products construction promote mainly kind, be one and compel in the problem solving and the best of strong No. a kind of mulberry is formed form fast and cut the time of cutting down, so study mulberry tree of strong mulberry, to form fast method be very useful.

Summary of the invention:

Object of the present invention is exactly for the deficiencies in the prior art, and provides mulberry tree of strong mulberry to form fast method.The present invention has and in the good situation of rich water quality management condition, grows vigorously, and year leaf yield is high, adopts within 2 years, just can form fast, technology is reliable, can reach the early object of income of early operation of silkworm raiser, and the summer is cut down leaf and can make silkworm in spring leaf, mulberry leaf availability improves, and silkworm raiser has increased the advantage of income.

Technology solution of the present invention is as follows:

Strong mulberry tree of mulberry is formed method fast, it is characterized in that: comprise the steps: (1) rational application of fertilizer; (2) summer is cut down the summer and cuts down.

In technique scheme, after described mulberry sapling is planted, the 1st year, when plant March, use base manure, mu apply barnyard manure (sheep fertilizer) 2000kg, impose night soil April 2 times, the first tenday period of a month in May mu sealing fertilizer 10kg, mid-June, mu sealing fertilizer 10kg, executed urea 30kg mid-July.The 2nd year, January barnyard manure 2000kg, late March is executed spring fertilizer, composite fertilizer 17kg adds urea 35kg, late June Xia Fei composite fertilizer 15kg.

In technique scheme, described the 1st year spring, after field planting, overhead 20cm cuts and cuts down, carry out bud thinning the first tenday period of a month in May, often select good strains in the field for seed and stay 2～3 of the strong buds that top growth is healthy and strong, adnation position is well-balanced, form 2～3 branches, early July, overhead the 45cm place summer is cut down (plucking core), forms the 1st branch, cuts the blue or green luxuriant leaf cutting down and makes summer silkworm leaf in five ages, early August bud thinning, 4～6 of strain messages, cultivate into the 2nd branch, and late November is carried out strong top clipping, the 2nd year phase in spring do not carry out the spring and cuts down, to late May overhead the 65cm place summer cut down and determine fist, 3～5 fists are stayed in every strain, form tree-like.

Beneficial effect of the present invention is:

The present invention grows vigorous in the good situation of rich water quality management condition, and year leaf yield is high, adopts within 2 years, just can form fast, technology is reliable, can reach the early object of income of early operation of silkworm raiser, and the summer is cut down leaf and can make silkworm in spring leaf, mulberry leaf availability improves, and silkworm raiser has increased income.

Embodiment:

The following stated is only preferred embodiment of the present invention, not scope of the present invention is limited.

Embodiment: see shown in Fig. 1 and Fig. 2, strong mulberry tree of mulberry is formed method fast, it is characterized in that: comprise the steps: (1) rational application of fertilizer; (2) summer is cut down the summer and cuts down.

After described mulberry sapling is planted, the 1st year, when plant March, use base manure, mu apply barnyard manure (sheep fertilizer) 2000kg, impose night soil April 2 times, the first tenday period of a month in May mu sealing fertilizer 10kg, mid-June, mu sealing fertilizer 10kg, executed urea 30kg mid-July.The 2nd year, January barnyard manure 2000kg, late March is executed spring fertilizer, composite fertilizer 17kg adds urea 35kg, late June Xia Fei composite fertilizer 15kg.
